User defined custom virtual keyboard

At present, the smart phones are mostly touch based, and they don't have an input hardware (keyboard) associated with them. Also, the software keyboard present in these smart devices, are very small as compared to desktop/laptop. This results in slow typing and also, causing inconvenience for the disabled people. In the smart devices (mobile, tablets, TV etc.), a hardware keyboard is missing. There are few solutions for making virtual keyboard but those solutions are not customizable and accurate enough with existing phone's hardware. Some solutions like laser keyboard which can be used as an alternative to hardware keyboard are there, but it requires an extra hardware to carry along with your device. Also, using specialized 3D cameras can be an alternative to the above problem. This paper defines new way of developing a virtual and custom keyboard, using 2D camera and other sensors available in phone, without the use of any extra input hardware. This implementation enables users to create his keyboard on any homogenous surface like table or paper.
